Description
Technical field
General conception of the present invention relates to the apparatus and method of handling the information of using the touch pad input, more particularly, relate to such processing and use the apparatus and method of the information of touch pad input, these apparatus and method make the user can use the direct input information of touch pad by touch pad is mapped as absolute coordinates with predetermined viewing area.
Background technology
User interface facilities (afterwards, being called input equipment) allows the user that desired information is input to computing machine.Keyboard is an example of the input equipment that is widely used.Keyboard comprises a plurality of buttons, its each all have from its output being mapped to the push button signalling of each numeral or character, thereby make the user easily desired information to be input to computing machine.Specifically, when using a computer Edit Document, keyboard allows the user to import desired character effectively, has developed various technology to strengthen user experience and to make computing machine have more purposes in computer industry.
Outside keyboard, the indicating equipment of also frequent use such as mouse, touch pad or touch-screen is as input equipment.When moving when display unit (for example, the display of computing machine) is gone up the cursor (for example, mouse pointer) that shows or selected specific icon, indicating equipment provides users with the convenient.
In recent years, the slip-stick artist had developed a kind of technology, wherein used the information of importing such as the indicating equipment of Microsoft's input method editing machine (IME) to be identified as character.For example, with the linking of documents editing application module in, IME will be character by the information Recognition of indicating equipment input and the character of identification offered the documents editing application module.
When using keyboard with such as Chinese, Japanese language character, or the Arabic character creates document when (it needs to be converted into (alphanumerical) schema document of alpha-numerical establishment subsequently), can use this technology easily and flexibly.When even the sounding of the character of input is difficult to and the user may not know the accurate sounding of the character imported and user when still importing the character that knocks into voice and ideograph, this technology may be particularly useful.
But conventional art has disadvantage.
At first, for input character, user's rolling mouse pointer is pressed the mouse button that is positioned on the mouse simultaneously.In this case, the user uses his or her wrist joint input character, and the quantity of using in this character of input of knocking makes that the efficient of input process is very low.In addition, because the out of true when using mouse is knocked, may produce wrong character.Particularly, when using mouse, it is many more to import the needed quantity of knocking of complicated more character, and it is low more that then character recognition efficient will become.Because these reasons, conventional art also suitably do not solve effective character recognition problem.
Simultaneously, touch pad is the indicating equipment as mouse, and it is widely used in notebook in light weight, that size is little.Compared with using mouse, can be identified more effectively and use as character such as the touch pad input of the marking tools of finger, joystick or pen.
But because touch pad carries out and the mouse function identical functions, so move with the mouse pointer that is used for the character input and move in order to distinguish common mouse pointer, the user must be provided by the mouse button that provides in touch pad when input character.
Now with reference to Fig. 1 the traditional operation that uses touch pad to come input character is described, wherein IME links with document editor 110.
The user uses the IME application program to come input character by IME input window 120.The user uses document editor 110 to come Edit Document.When showing IME input window 120, the user contacts dilatory marking tools under the state of touch pad (1) and moves the mouse pointer 130 that shows to IME input window 120 on display unit at marking tools.
Provide the input be known as Hangul Korea character '
(Ka) ' as an example, '
(Ka) ' comprise three elements, that is, and ' ', '
' and '-'.
After mouse pointer 130 was moved to IME input window 120, the user pressed mouse button in the dilatory marking tools on touch pad, and imports first element ' ' (2).
For import second element '
', mouse pointer 130 should be moved to position ' a '.For this reason, the user discharges the pressure that is applied on the mouse button, dilatory marking tools on touch pad, and rolling mouse pointer 130 is to position ' a ' (3) then.
When the position ' a ' of mouse pointer 130 on display unit, the user presses mouse button in the dilatory marking tools on touch pad, and import second element '
' (4).
In order to import the 3rd element '-', the user discharges the pressure that is applied on the mouse button, dilatory marking tools on touch pad, and rolling mouse pointer 130 is to position ' b ' (5) then.
When mouse pointer 130 in the position when ' b ', user's dilatory marking tools on touch pad is pressed mouse button simultaneously, and imports the 3rd element '-' (6).
In the prior art, when the user used touch pad to come input character, the user must operate mouse button with input character and rolling mouse pointer simultaneously when repeatedly drawing marking tools.Last from the time, this operator scheme becomes more and more heavier for the user.Therefore, along with the increase of character number of taps, the user inconvenience related with using the touch pad input character has just increased inevitably.This is because the whole viewing area of touch pad and display unit is corresponding with relative coordinate.
Simultaneously, in using the situation of touch-screen, the user can be directly the touch-screen inputing characters just as the user uses pen actual writing.But touch-screen is expensive indicating equipment, therefore is not suitable for by the widely used cheap personal computer of domestic consumer (PC).
The open No.2003-196007 (character input device) of Jap.P. discloses a kind of technology, its permission shows dummy keyboard on display unit, and the user uses touch pad rolling mouse pointer and input on dummy keyboard to be mapped to the character of dummy keyboard.But in the situation of language, still be difficult to all base characters are mapped on the button that provides on the dummy keyboard with a large amount of base characters.In addition, because the user must one by one seek desired character on dummy keyboard, not that very skilled user may run into inconvenience so use dummy keyboard.
Therefore, similar with the situation of using touch-screen, need better technology so that user's direct information uses touch pad and is transfused to.

Embodiment
Present with careful embodiment with reference to general conception of the present invention, its example shown in the drawings, wherein identical Reference numeral is indicated components identical in the text.Be described below embodiment in the reference accompanying drawing, to explain general conception of the present invention.
The embodiment that Fig. 2 shows the general conception according to the present invention uses the block scheme of the device of touch pad input information.
The device of Fig. 2 comprises touch panel unit 210, key-press input unit 220, control module 230 and display unit 240.This device also comprises storage unit 250, recognition unit 260 and image generation unit 270.
For example, when touch pad 212 is the pressure sensitive type, constitute touch pad 212, between these two resistor discs, meticulous gap is arranged by two earth resistance sheets that overlap each other.When marking tools contact touch pad 212, resistor disc contacts with each other at this point, and electric current flows through between resistor disc.In response to the contact of marking tools, touch pad 212 produces simulating signal and exports this signal to coordinate processing unit 214.Coordinate processing unit 214 extracts to be exported as digital signal about the information of corresponding contact position and with this information.Therefore, if when with touch pad 212 (more particularly, dilatory marking tools when the contact area of touch pad 212) contacting, then coordinate processing unit 214 can detect the mobile route of contact point, produce the contact position coordinate corresponding, and the contact position coordinate that output is produced is to control module 230 with mobile route.
But employed touch pad is not limited to the touch pad of pressure sensitive type in general conception of the present invention, can also comprise the other types device that can detect contact and output contact position coordinate.
Key-press input unit 220 can comprise that at least one button and output and the button corresponding key signal pressed are to control module 230.The input information that each push button signalling is mapped to numeral, character or has specific function.Therefore, the user can operation push-button input block 220 and the touch pad input pattern is set to relative coordinate pattern or absolute coordinates pattern.
More particularly, control module 230 can comprise that coordinate is provided with unit 232, coordinate transformation unit 234 and mouse pointer control module 236, as shown in Figure 3.
If the touch pad input pattern is the relative coordinate pattern, then coordinate whole viewing area that unit 232 touch pads 212 and display unit 240 be set is set to correspond to each other, as relative coordinate.In this case, if dilatory marking tools when contacting with touch pad 212, then coordinate transformation unit 234 is a relative coordinate with the contact position coordinate conversion, and the contact position coordinate is corresponding with the change between the contact position of marking tools before the dilatory operation and afterwards.Mouse pointer control module 236 moves the mouse pointer that is presented on the display unit 140 according to the contact position coordinate of being changed.
In this case, using the mobile of mouse pointer of touch pad 212 is to carry out according to the method identical with classic method.That is, in the relative coordinate pattern, the position of using the mouse pointer that display unit 240 shows only changes in the situation of the specified point of the touch pad 212 of marking tools contact therein.Therefore, in order to change the position of mouse pointer, when contact touch pad 212, must in the relative coordinate pattern, draw marking tools.
If the touch pad input pattern is the absolute coordinates pattern, then coordinate is provided with unit 232 touch pad 212 is set, or more particularly, the input area of touch pad 212 and the particular display area of display unit 240 is set corresponds to each other, as absolute coordinates.So, 1:1 ground is mapped to this particular display area with touch pad 212.
In this case, coordinate transformation unit 234 will be an absolute coordinate from the contact position coordinate conversion of touch panel unit 210 inputs.Mouse pointer control module 236 is controlled moving of mouse pointer on the viewing area that is mapped to touch pad 212 according to the contact position coordinate of being changed.Figure 4 illustrates its example.
With reference to Fig. 4,, mouse pointer 310 restrictions are used as absolute coordinates are mapped in the viewing area 242 of touch pad 212 if be provided with absolute coordinates.Therefore, the mouse pointer on viewing area 242 310 moves and follows according to absolute location coordinates with the path that the dilatory path (dilatory path) 340 thereon of marking tools 330 is identical across touch pad 212.In this case, for the dilatory path 340 of marking tools 330, mouse refers to that 310 mobile route 320 is corresponding to the area part of touch pad 212 ratio value with respect to viewing area 242.
Be different from the relative coordinate pattern, in the situation of absolute coordinates pattern, if marking tools 330 contact touch pads 212 just then can be placed on mouse pointer 310 on the coordinate with contact point corresponding display 242.
Similarly, the viewing area 242 that is mapped to touch pad 212 can be corresponding with the part viewing area of the whole viewing area of display unit 240 or display unit 240, as absolute coordinates.So, when the user carries out application-specific to computing machine, mouse pointer 310 is restricted to the viewing area, for example, shown execution pop-up window when using Microsoft's Window family computer operating system (OS).The executing state of application program is presented in this window.Similarly, the user can use touch pad 212 direct rolling mouse pointer 310 in corresponding viewing area.
Mouse pointer control module 230 touch pad 212 is therein shown the mobile route of mouse pointer 310 on the viewing area that is mapped to according to absolute coordinates.For example, when the dilatory marking tools of user 330 during, as shown in Figure 4, the mobile route 320 of mouse pointer 310 can be shown to the user visibly across touch pad 212.
When selected operator scheme is the absolute coordinates pattern, control module 230 will be an absolute coordinates from the contact position coordinate conversion of touch panel unit 210 outputs, and storage unit 250 is stored the contact position coordinate of being changed.In this case, before carrying out the identification of being undertaken by recognition unit 260 or before the generation image that execution is undertaken by image generation unit 270, in the time of will being absolute coordinates from the contact position coordinate conversion of touch panel unit 210 outputs by control module 230, storage unit 250 is with the contact position coordinate of one group of storage conversion.Therefore, when after the identification that carry out to use recognition unit 260 to carry out or carry out and use after image generation unit 270 carries out the image generation, in the time of will being absolute coordinates from the contact position coordinate conversion of touch panel unit 210 outputs by control module 230, storage unit 250 is stored as new group with the contact position coordinate of conversion.In storage unit 250, will have as the combination of the contact position coordinate of a group storage be formed in wherein the viewing area that touch pad 212 is shone upon according to absolute coordinates on the identical coordinate figure of coordinate of mobile route of the mouse pointer that shows.
The combination that recognition unit 260 uses formation to be stored in one group contact position coordinate in the storage unit 250 comes identification character.For this reason, recognition unit 260 can be stored the standard character as the benchmark of the various characters of identification.Recognition unit 260 search has the standard character that the maximal correlation degree is arranged with the contact position coordinate, and the standard character that is searched is identified as the user wants character or the mark imported.Recognition unit 260 can use traditional character recognition technologies to carry out identification.
When marking tools does not contact touch pad 212 in the time of growing at interval than threshold time, can carry out identifying operations by recognition unit 260.Perhaps, when using key-press input unit 220, touch panel unit 210 or other user interface section (not shown) input recognition command, can carry out identifying operation.
The image data storage that produced can be presented on the display unit 240 in storage unit 250 and according to user's request.
The method of processing touch pad input information of the embodiment of the general conception according to the present invention is described now with reference to accompanying drawing.
The embodiment that Fig. 5 shows the general conception according to the present invention handles the process flow diagram of the method for touch pad input information.
In operation S110, the touch pad input pattern initially is set by the user.Can use key-press input unit 220, touch panel unit 210 or other user interface section (not shown) to import input pattern order is set.
In operation S120, coordinate is provided with unit 232 and determines whether input pattern is the absolute coordinates pattern.Be set to the absolute coordinates pattern if determine input pattern, then at operation S130, coordinate is provided with unit 232 input area and the predetermined display area on display unit 240 of touch pad 212 is mapped as absolute coordinates.So, with the input area 1:1 of touch pad 212 be mapped to predetermined viewing area.
The S140 marking tools contacts touch pad 212 and from touch pad 212 outgoing position coordinates, then touch panel unit 210 outputs to coordinate transformation unit 234 with the contact position coordinate if operating.At operation S150, coordinate transformation unit 234 will be an absolute coordinates from the contact position coordinate conversion of touch panel unit 210 outputs then.At operation S160, mouse pointer control module 236 is according to the contact position coordinate of being changed from the mapping area of touch pad 212 by coordinate transformation unit 234, rolling mouse pointer 310 on viewing area 234.
If set input pattern is not absolute coordinates pattern but relative coordinate pattern, then at operation S165, coordinate is provided with unit 232 touch pad 212 is mapped as the whole viewing area of display unit 240, as relative coordinate.
If at operation S170 marking tools contact touch pad 212 and from touch pad 212 outgoing position coordinates, then touch panel unit 210 outputs to coordinate transformation unit 234 with the contact position coordinate and coordinate transformation unit 234 will be a relative coordinate from the contact position coordinate conversion of touch panel unit 210 outputs.At operation S190, mouse pointer control module 236 according to by the contact position coordinate of coordinate transformation unit 234 conversions on display unit 240 rolling mouse pointer 310.
If the operation S160 in the absolute coordinates pattern rolling mouse pointer 310, then mouse pointer control module 236 can use display unit 240 to show the mobile route of mouse pointer on the viewing area.
The embodiment of general conception according to the present invention can store the contact position coordinate by coordinate transformation unit 234 conversions, and the contact position coordinate of being stored can be identified as character afterwards, describes this situation now with reference to Fig. 6 and 7.
The embodiment that Fig. 6 shows the general conception according to the present invention comes the process flow diagram of the method for identification character.
In operation S210, if export the contact position coordinates from touch panel unit 210 in the absolute coordinates pattern, then at operation S220, coordinate transformation unit 234 is an absolute coordinates with the contact position coordinate conversion.
In this case, storage unit 250 is converted to the contact position coordinate of absolute coordinates by coordinate transformation unit 234 in operation S230 storage.
If do not import recognition command, then repeatedly carry out the operation S210 that uses S230 operation S240 user.In this operation, storage unit 250 will be stored as a group with the contact position coordinate of having stored before together by the contact position coordinate that coordinate transformation unit 234 is changed recently.
If imported recognition command operation S240 user, then recognition unit 260 is by coming identification character as one group of contact position coordinate of storing in storage unit 250 in operation S250.
If the new contact position coordinate of coordinate transformation unit 234 conversions after character recognition, then storage unit 250 is stored as new group with the contact position coordinate of being changed.Therefore, all the contact position coordinates that will be changed before another character recognition process of execution are stored in identical group.
Another embodiment that Fig. 7 shows the general conception according to the present invention carries out the process flow diagram of the method for character recognition.
At operation S310, if export the contact position coordinates from touch panel unit 210 in the absolute coordinates pattern, then at operation S320, coordinate transformation unit 234 is an absolute coordinates with the contact position coordinate conversion.
In this case, at operation S330, storage unit 250 will be stored by the contact position coordinate that coordinate transformation unit 234 is converted to absolute coordinates.
If not from touch panel unit 210 output contact position coordinates, then at operation S340, in being no more than threshold time interlude interval, recognition unit 260 is waited for will be from the new contact position coordinate of touch panel unit 210 outputs at operation S310.If the stand-by period does not surpass threshold time at interval,, repeat operation S310 then by S340.If the stand-by period is no more than threshold time at interval, then the contact position coordinate that will be changed recently by coordinate transformation unit 234 of storage unit 250 and the contact position coordinate of having stored are before stored as one group together.
If the stand-by period has surpassed threshold time at interval in operation S350, then in operation S360, recognition unit 260 uses the contact position coordinate of storage in storage unit 250 to come identification character.
If by the new contact position coordinate of coordinate transformation unit 234 conversions, then storage unit 250 is stored as new group with the contact position coordinate of being changed after character recognition.Therefore, all the contact position coordinates that will be changed before carrying out another character recognition process all are stored in this identical group.
In this way, the embodiment of general conception according to the present invention, the dilatory operation (3 and 5) that can in character input process shown in Figure 1, omit the marking tools of the position that is used to change mouse pointer.Therefore, the user can use touch pad to write or use the mode of finger to come direct input character with pen with she or he.
After character recognition, will be stored in the storage unit 250 as new group as absolute coordinates by the new contact position coordinate of control module 230 conversions.
Though described character recognition process with reference to Fig. 6 and 7, can come discriminating digit and other symbols with the identical operations that illustrates previously.
Another embodiment of general conception according to the present invention, can use in storage unit 250 storage a set of contact position coordinates and with the shown mobile route storage of mouse pointer as view data.In this case, can carry out the image that uses image generation unit 270 and produce operation, rather than at the operation S250 of the character recognition shown in Fig. 6 with at the operation of the character recognition shown in Fig. 7 S360.
